通过Python发送视频文件
我需要弄清楚怎么写一个脚本，去扫描一个文件夹里的新文件，如果有新文件，就通过邮件发送这个文件。
我住的公寓里有人一直在偷自行车！最开始是我自己的错（我忘了锁车），现在那个小偷更厉害了，直接把锁链剪了。我真是受够了，尤其是当他用半英寸的飞机钢丝剪掉我的第二辆自行车的时候。
总之，我想用树莓派做一个运动感应的监控摄像头，希望它在录制完视频后，能立即把视频文件发给我。这样如果他们把树莓派也偷走，我还能有证据。
我在看一些例子，但我搞不清楚怎么让这个脚本一直运行（每分钟检查一次），或者怎么让它扫描一个文件夹找新文件。
好的，我已经把它简化到扫描文件然后尝试发送邮件的步骤了。但是在尝试附加视频文件的时候失败了。你能帮我吗？这是我修改后的代码：
失败信息是：
msg = MIMEMultipart()
TypeError: 'LazyImporter' object is not callable, line 38

只需把你的脚本放在一个循环里，然后让它每60秒“睡一觉”。你可以用 glob 来获取目录中的文件列表。in 这个东西很有用，可以用来查看列表里的内容（也就是目录中的文件列表）。
import time, glob
files=glob.glob("/home/me/Desktop/*.mp4") #Put whatever path and file format you're using in there.
while 1:
new_files=glob.glob("/home/me/Desktop/*.mp4")
if len(new_files)>len(files):
for x in new_files:
if x not in files:
print("New file: "+x) #This is where you would email it. Let me know if you need help figuring that out.
files=new_files
time.sleep(60)

我用的是python3，怎么也搞不定这些例子，但我想出了一个简单得多的方法，结果可以正常工作。
import smtplib
from email.message import EmailMessage
from email.mime.base import MIMEBase
from email import encoders
# Defining Objects and Importing Files ------------------------------------
# Initializing video object
video_file = MIMEBase('application', "octet-stream")
# Importing video file
video_file.set_payload(open('video.mkv', "rb").read())
# Encoding video for attaching to the email
encoders.encode_base64(video_file)
# creating EmailMessage object
msg = EmailMessage()
# Loading message information ---------------------------------------------
msg['From'] = "person_sending@gmail.com"
msg['To'] = "person_receiving@gmail.com"
msg['Subject'] = 'text for the subject line'
msg.set_content('text that will be in the email body.')
msg.add_attachment(video_file, filename="video.mkv")
# Start SMTP Server and sending the email ---------------------------------
server=smtplib.SMTP_SSL('smtp.gmail.com',465)
server.login("person_sending@gmail.com", "some-clever-password")
server.send_message(msg)
server.quit()

看起来，email模块随着时间的推移进行了重构。 这解决了我在Python 2.7中遇到的'LazyImporter'对象不可调用的错误：
from email.mime.text import MIMEText
值得注意的是，它对我认为是同义词的写法，比如import email; email.mime.text.MIMEText(...)并不满意。

我终于搞定了。为了消除LazyImporter错误，我不得不使用Python 2.5。每当在安全文件夹里添加一个新文件时，它就会发邮件通知我。不过，日志功能坏掉了。
